3.6.6 Thermistor Resistance

The resistance of the thermistor at the operating temperature T

(°C) is determined using the following

equation (7).

Equation (7):

: Resistance at operating temperature Tx (°C)

: 30 kΩ ± 5% (25°C)

B: 3950 K ± 2 %

: Operating temperature (°C)

EXP (A) : The Ath power of natural logarithm e (2.71828)

[Rating]

Operating temperature range: -40 °C to +125 °C
